Description

Technical Field

[0001] This application relates to the field of bucket wheel stacker reclaimers, and more particularly to a protective device for the bucket teeth of a bulk material stacker reclaimer. Background Art

[0002] The bucket wheel stacker reclaimer is a rail-mounted loading and unloading device that combines stacking and reclaiming, developed on the basis of a small bucket wheel excavator. It is mainly used for the stacking, reclaiming, conveying, and leveling of bulk materials in industries such as thermal power plants, mines, ports, steel, cement, etc., as well as large-scale water conservancy sites. It has the advantages of large stacking and reclaiming capacity, small occupied area of the stockyard, convenient operation, and easy realization of automatic control, and is widely used in the industrial sector. The bucket wheel stacker reclaimer belongs to a large-scale and efficient stacking and reclaiming device and has started to develop in the direction of large-scale and automation. As a reclaiming machine, the bucket wheel bucket is a consumable part, and its service life is particularly important. The bucket teeth, as important components on the bucket, directly affect the overall service life of the bucket and the working efficiency of the bucket wheel stacker reclaimer. For example, a bucket tooth of a bucket wheel stacker reclaimer with Chinese patent application number CN201820035774.1 includes an integrally arranged tooth tip part and a mounting part. The lower surface of the tooth tip part is a first inclined surface that slopes downward from top to bottom. The mounting part includes an upper clamping arm and a lower clamping arm. The inner walls of the upper clamping arm, the lower clamping arm, and the inner wall of the tooth tip part enclose a clamping groove. Multiple bolt holes are provided on the upper clamping arm, and an extended protection section is integrally arranged on the lower clamping arm. A nut protection hole is provided on the extended protection section. Its advantages are good strength, extended service life of the bucket teeth, convenient installation / dismantling, labor saving, reduced production costs. The nut protection hole on the extended protection section protects the nut from external surface wear, so that it cannot be unscrewed and disassembled using a socket wrench; it also prevents the bolts and nuts from slipping, falling off, or even breaking under force, thus preventing the bucket teeth from loosening and falling off.

[0003] However, the above solution still has certain defects: Firstly, it is not convenient to protect the surface of the bucket teeth, resulting in the need to replace the bucket teeth after a period of use, increasing resource waste and thus reducing practicality. Summary of the Utility Model
